Photos: Alzheimer’s disease: 7 issues that increase your risk The study discovered that tau protein, which shows the fibrous tangles found in the brains of Alzheimer’s individuals, spreads along the brain’s neurons from one area to the other – leading to severe dementia. The new clues to the neurodegenerative human brain disorder might help scientists find a way to stop the condition from getting worse.
Amyloid plaques are sticky deposits made up of a brief protein known as amyloid beta, and tau tangles are constructed with brief filaments of the tau protein. So far no one has had the opportunity to explain how amyloid beta and the tau tangles wreak their harm on the nervous system. ‘We have known for a long time that amyloid beta was poor,’ said Scott Brady, head and professor of anatomy and cell biology in the UIC College of Medicine. ‘What we haven’t comprehended is why it’s bad.’ The findings, reported in a fresh study showing up in the Proceedings of the National Academy of Sciences Online Early Edition for March 16-20, suggest promising fresh targets for combination therapy.
